Harness Oia Audit

What it does

When your agent uses it

• Tasks that involve Scheduled and recurring tasks
• Tasks that involve Threat modeling
• Tasks that involve Architecture decision records

Example prompts

• “/harness-oia-audit”

Requirements

• Node.js
• Pre-approved tools (allowed-tools): Bash

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Run harness oia-manifest — Open Infrastructure Architecture
2. 2Run harness threat-model — categorized MCP-surface threat
3. 3Run harness mcp-scan — per-server/tool policy + permissions
4. 4Composite worst = max(threatModel.worst, max(mcpScan.findings.severity)).
5. 5Persist payload to memory namespace metaharness-audit with key
6. 6alert-on-worst : exit 1 if composite worst ≥ threshold.

What it can do on your machine

Read from SKILL.md and the folder at commit 6c04654. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Bash

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • npx

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Harness Oia Audit loads about 720 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 219 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~61

When it runs · the whole SKILL.md, loaded when a task matches

~720

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

  allowed-tools: Bash

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Composite Phase-2 audit worker (ADR-150). Bundles harness oia-manifest + threat-model + mcp-scan into one timestamped audit record stored in the `metaharness-audit` memory namespace. Designed for cron-scheduled drift detection.
